Yia Yia Mary has always said that when it comes to berries, "wash as you eat otherwise they go off".
Turns out, she was right! Berries have a protective layer on them called 'bloom' that is produced naturally to ward off insects and bacteria. If this layer is removed, it limits the life of the berries.
So only wash your berries when you plan to eat them to keep them lasting longer in your fridge!
